TEMPORARY BINDER.

To all whom it may concern:

Be it known that we, CLARENCE D. TnUs- SELL and EMORY A. TRUSSELL, both citizens of the United States, both residing in the borough of Manhattan, New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Temporary Binders, of which the following is a specification.

Our invention relates to temporary binders for blank books, account and memorandum books, and the like, in which the leaves may be inserted or removed at will.

The object of our invention is to provide a temporary binder of inexpensive, simple and strong construction which will present a neat appearance and which may be readily opened for the withdrawal or insertion of leaves and readily closed for the retention of the leaves.

Figure 1 of the drawings is a perspective view of our temporary binder, the covers being opened and the sheet-holding prongs being closed but no leaves being shown. Fig. 2 is a sectional view on the line 22 of Fig. 1, the sheet-holding prongs being in closed position. Fig. 3 is a view similar to Fig. 2, the sheet-holding prongs being shown in open position. Fig. 1 is a plan view of the metallic parts of the device, the leather covers etc., being omitted.

Referring to the drawings, 1 represents the covers of our temporary binder having the back 2. Lying inside the back is the curved spring-plate 3 provided with the inturned longitudinal wings 4 having oppositely arranged pairs of notches 5, adapted to receive the sheet-holding prongs 6 each half of which is notched at 7 to engage the edge of a notch 5 in a longitudinal wing t of the spring-plate 3. The two halves of each pair of sheet-carrying prongs 6 have at their lower ends the male and female joint 8, and adjacent to the same is the plane surface 9. The operating rod 10, provided with the upturned handle 11, extends along the spring-plate 3 underlying the several Specification of Letters Patent.

pairs of sheet-holding prongs. The rod 10 is cut away or notched, as best illustrated at 12 in Figs. 2 and 3. The metallic binding plate 13 is secured to spring-plate 3 by ears 14 which extend from said binding plate 13 through apertures in the spring-plate 3. The binding strip 15 is held securely between the binding-plate 13 and spring-plate 3, as best illustrated in Figs. 2 and 3, and extends on either side within the covers as indicated.

The operation of the device is as follows: Vhen the parts are in the position indicated in Fig. 2, the resiliency of spring-plate 3 holds the outer ends of the sheet-holding prongs together to retain the leaves, inasmuch as the joint between said prongs is located below the points of engagement be tween the sheet-holding prongs and springplate 3. In this position the flat surface 9 of each pair of sheet-holding prongs rests in a notch 12 in operating rod 10. mien, however, the upwardly turned handle 11 is shifted into the position illustrated in Fig. 3, each notch 12 is turned sidewise so that the unnotched, straight surface of rod 10 engages the flat surface 9 to throw the same upward and separate or open the prongs which are held open until the handle 11 is shifted back into its initial position, indicated in Fig. 2, to close the prongs. Throughout this operation the resiliency of spring-plate 3 tends constantly to close the sheetholding prongs which are forced and retained open merely by the eccentric movement of the notches 12 in the operating rod 10.

It will be seen that our device has few and simple metallic parts which are not liable to get out of order. The prongs are carried on integral wings of the spri11gplate itself, so that the operating parts consist merely of the spring-plate, the prongs and the operating rod 10. The notches 12 retain the rod 10 in position except when the same is rotated to open the prongs. In this position, however, the downward pressure of the prongs holds the rod 10 fast. It may, however, be Withdrawn by a strong outWard pull in case the parts should for any reason need adj ustment.

What We claim as new and desire to secure by Letters Patent is:

In a temporary binder, a spring plate, mating prongs carried thereon, and an operating device provided With an eccentric surface for each pair of prongs the movement of Which opens the prongs against the pressure of the spring plate.
